A  FEW  WORDS  ON  PULLEYS 

The  following  four  pages  should  be  carefully  studied  before  order- 
ing pulleys,  and  care  should  be  used  to  select  the  proper  style  and  size 
of  pulley  to  best  meet  the  requirements  of  the  case.  When  in  doubt 
specify  the  conditions  to  be  met  and  we  will  furnish  the  pulleys  most 
suitable. 

We  offer  four  styles  of  Pulleys. 


Steel  Rim  Pulleys  (Whole  or  Split) 
CAST  IRON  PULLEYS  (Whole  or  Split) 
AMERICAN  Pressed  Steel  Split  and 
GILBERT  Wood  Split,  Pulleys. 

FACES  —  The  faces  of  all  pulleys  are  made  wide  enough  to  carry  belts 
of  nominal  width  of  face  given  in  price  lists.  Crowning  faces  are 
always  furnished  unless  Straight  faces  are  ordered. 

HUBS—  Standard  Cast  Iron  and  M&(&  Steel  Rim  Pulley  hubs  (with- 
out bushings)  will  be  faced  or  furnished  to  exact  lengths  at  a 
slight  additional  charge.  See  table  of  standard  hub  lengths  on 
pages  33  and  51. 

LARGE  BORES  —  Pulleys  with  extra  large  bores  are  subject  to  an 
extra  charge.  See  table  of  Bore  Limits  on  page  57. 

HIGH  SPEED  PULLEYS—  The  maximum  peripheral  speed  for  cast 
iron  pulleys  is  about  5000  feet  per  minute. 

When  pulleys  are  wanted  for  rim  speeds  over  3000  feet  per  minute 
it  should  be  mentioned  when  ordering  as  special  balancing  is  nec- 
essary and  for  which  an  extra  charge  is  made. 

LAGGING  —  We  can  furnish  pulleys  covered  with  leather,  rubber  or 
canvas  to  meet  any  requirement.  See  partial  list  on  page  55. 

SPECIAL  PULLEYS—  Special  pulleys  of  any  kind,  or  with  special 
hubs,  or  in  any  way  departing  from  our  standards  will  be  quoted 
on  upon  receipt  of  sketch  showing  just  what  is  wanted.  See 
definition  of  "Special  Pulleys"  on  pages  14  and  15.

A  FEW  WORDS  ON  PULLEYS  (Continued) 

KINDLY  CONSIDER 

That,  to  fill  orders  correctly,  it  is  absolutely  necessary  to  mention 
Diameter,  Face  and  Bore,  also  whether  pulleys  require  a  straight  or 
crowning  face.  Unless  specifically  otherwise  ordered,  pulleys  are  fur- 
nished with  a  crowning  face. 

NOTE — When  belt  has  to  be  shifted  on  a  pulley  to  drive  tight 
and  loose  pulleys,  the  face  of  the  driving  pulley  for  same  must  be 
straight.  Tight  and  loose  pulleys  always  have  crowning  faces. 

All  pulleys  used  for  Belt  Tighteners  should  be  ordered  straight 
face. 

Be  careful  to  send  the  exact  diameter  of  the  shaft — for  example, 
!}-§  inches  exact,  or  2  inches  exact  (both  of  these  sizes  are  usually 
termed  2  inch  shafting,  and  it  is  therefore  very  important  to  state 
the  exact  size  required).  This  rule  holds  good  for  all  sizes,  and  strict 
attention  to  it  will  result  in  the  avoidance  of  expensive  errors. 

In  ordering  always  give  diameter  first,  then  face,  (crown  or  straight) 
then  bore,  thus — one  HI&OI  Steel  Rim  Pulley  36  by  10  crown, 
2|J  bore. 

Also  specify  whether  pulley  is  to  be  whole  or  split,  or  whole  rim 
and  split  hub  (Clamp  Hub  Pulleys),  also  whether  it  is  to  be  key  seated 
or  to  be  held  with  set  screws,  and  if  to  be  keyseated,  give  exact  width  of 
keyseat  if  special.  Width  of  standard  keyseat  is  approximately  % 
of  diameter  of  shaft.  See  table  of  standard  key  seats  on  page  85. 

Pulleys  ordered  keyseated  are  always  supplied  with  straight 
keyway  (sometimes  called  a  feather  way)  with  set  screws  over  it  unless 
taper  keyseat  or  taper  keyway  is  specifically  ordered. 

For  rule  to  figure  speeds  and  sizes  of  pulleys  see  page  149. 

For  table  of  horsepower  of  pulleys  see  page  148. 

For  table  of  horsepower  of  belting  see  pages  132  and  133.

DEFINING  SPECIAL  PULLEYS 

Many  of  our  customers  order  pulleys  having  diameters  or  faces 
running  into  fractions  of  inches  (for  example:  17/^  diameter  by  12^4 
face) . 

The  practice  heretofore  followed  of  charging  for  such  fractional 
size  pulleys  by  taking  the  next  larger  size  or  face  listed  in  catalog  has 
been  found  inadequate  to  meet  the  excessive  cost  of  such  SPECIAL 
PULLEYS. 

Our  moulding  machines,  pulley  rings,  arms,  etc.,  are  all  made 
according  to  certain  standards  covered  by  sizes  in  our  pulley  lists 
and  even  a  slight  departure  from  sizes  given  necessitates  special 
work,  pattern  work,  lagging  up  pulley  rings  to  increase  diameters, 
excessive  thickness  of  rim,  extra  machine  work,  etc.,  and  always  en- 
tails a  far  greater  cost  of  production  than  can  possibly  be  covered  by 
charging  at  the  price  of  the  next  larger  size  listed. 

However,  when  any  departure  from  standard  pulleys  is  insisted 
on,  pulleys  will  be  considered  "SPECIAL"  and  subject  to  an  extra 
charge  ranging  from  10%  up,  depending  on  the  amount  of  extra 
work  and  material  involved. 

To  keep  down  manufacturing  costs  and  therefore  avoid  extra 
charges  we  would  request  that  customers  confine  themselves  whenever 
possible  to  LISTED  SIZES,  both  in  diameter  and  face,  as  faces  are 
always  wide  enough  to  accommodate  belts  of  face  width  listed  and 
there  are  but  few  mechanical  conditions  where,  for  instance,  a  14-inch 
diameter  pulley  will  not  work  precisely  as  well  as  a  13>^-inch,  13 y^- 
inch  or  14^ -inch  diameter  pulley,  especially  when  it  is  recalled  that 
the  best  belt  drives  usually  involve  some  2%  slip,  and  that  loose  or 
poor  belts  slip  a  great  deal  more.

STEEL  RIM  SPLIT   PULLEYS 
With  Interchangeable  Bushings 


THE  FINAL  PULLEY 


The  new  4H&05  Steel  Rim  Split  Pulley  shown  above  is  a  Split 
Pulley  of  the  interchangeably  bushed  type  with  all  the  weaknesses 
of  this  type  of  pulley  left  out. 

It  is  not  solely  made  of  wood,  or  iron,  or  of  steel,  but  is  a  logical 
combination  of  the  latter  two  materials. 

Iron  in  the  hub  and  arms  to  make  it  rigid  where  it  should  be  so 
and  Wrought  Steel  in  the  rim  where  lightness  and  toughness  are  the 
qualities  required. 

The  rim  is  substantial — not  thin  sheet  metal  requiring  a  beaded 
edge,  but  heavy  wrought  steel  that  you  can  see  and  feel — and  besides 
it  is  sustained  at  many  points  by  the  numerous  arms  of  the  rigid  cast 
spider  within. 

The  parting  points  are  secured  with  a  special  taper  lock  joint 
(patented) — the  strongest  and  safest  joint  ever  devised  for  a  part- 
ing pulley  of  this  kind. 

Interchangeable  bushings  are  supplied  to  fit  pulley  to  shaft 
when  shaft  is  smaller  than  the  normal  bore  of  the  pulley. 

fH &(&  steel  rim  split  pulleys  grip  the  shaft  like  a  vise  and"  require 
no  keys  though  keys  may  be  used  in  unusually  severe  drives  if  desired. 

See  constructional  features  and  price  lists  on  the  following  pages.

<&   STEEL  RIM  SPLIT  PULLEYS 

With  Interchangeable  Bushings 
(Continued) 


In  the  manufacture  of  the  fB&CS  Steel  Rim  Split  Pulleys  the 
central  "spiders"  are  cast  complete,  and  being  without  rims,  are 
entirely  free  from  shrinkage  strains.  The  hubs  are  then  bored  and 
the  ends  of  the  arms  ground  off  from  a  common  center  on  especially 
devised  machines. 

The  Steel  Rims  are  then  rolled  and  firmly  riveted  in  place,  after 
which  the  pulleys  are  mounted  on  mandrils  and  the  surface  and  edges 
of  rims  ground  dead  true. 

Hubs  are  then  split,  pulleys  balanced  and  painted  and  they  are 
ready  for  your  line  shaft. 

The  new  itt^Cfj  Steel  Rim  Split  Pulley  is  the  culmination  of 
twenty-five  years  of  experience  in  pulley  building  by  the  largest 
manufacturers  of  pulleys  in  the  West  and  the  result  is  a  pulley  that 
is  as  nearly  perfect  as  a  pulley  can  be — free  from  the  excessive  weight 
of  cast  iron,  yet  very  substantial  and  much  safer  in  its  construction — 
powerful  in  operation — handsome  in  appearance — adaptable  to 
different  shafts — as  round  as  a  dollar — quick  in  delivery  and  low 
in  price.

IT'S  IN  THE  JOINT,  where  most  split  pulleys  are  weak.  It's 
the  joint  wherein  the  danger  lies,  for  whether  it  be  a  Wood  Pulley, 
Cast  Iron  Pulley,  or  Steel  Pulley  of  any  make,  the  joint  is  usually  the 
weakest  part — the  part  that  means  destruction  and  sometimes  death 
when  things  go  wrong. 

STUDY  THE  JOINT  on  the  newltt&Ci;  Steel  Rim  Split  Pulley 
(Patented) — it  cinches  up  with  a  wedge-like  action  and  is  one  of  the 
strongest  reasons,  in  these  days  of  "Safety  First,"  why  the  itt  X- 0> 
Steel  Rim  Split  Pulley  is  the  onlyproper  pulley  for  your  industrial  plant. 

A — One  side  of  heavy  steel  rim  firmly 
riveted  to  the  special  steel  angle  B. 

D — Other  half  of  rim,  riveted  to  the 
arm.  When  drawn  together  by  means 
of  large  bolts  E,  the  rim  sections  are 
forced  into  perfect  alignment  by  reason 
of  the  taper  joint  C,  which  being  sup- 
ported by  a  rigid  arm  is  proof  against 
the  outward  pull  of  centrifugal  force  or 
the  inward  pressure  of  the  belt. 

A  slight  modification  from  the  above 
is  made  on  small,  narrow  face,  one 
bolt  pulleys.

STEEL  RIM  WHOLE  PULLEYS 


This  style  of  pulley  consists  of  a  central  spider  of  cast  iron,  to 
which  a  steel  rim  is  firmly  riveted,  a  construction  which  produces  a 
pulley  greatly  superior  to  a  cast  iron  pulley,  for  the  following  reasons: 

1.  These  pulleys  are  absolutely  free   from    shrinkage    strain,  as 
the  hubs  and  arms  are  first  cast  without  rims.     The  "spiders"  are 
centered    and  the  hubs  bored,  the  arms    are    then    ground   concen- 
trically with    the  axis,  after  which  the  steel  rims   are  attached  and 
ground  from  the  same  centers. 

2.  They    combine    the    minimum    weight    with    the    maximum 
strength,  being  from  40  to  60  per  cent  lighter  than  cast  iron  pulleys 
for   similar  duty — also   considerably  cheaper. 

3.  The  rims  being  of  wrought  steel,  of  even  thickness,  insure  a 
pulley,  which  in  regard  to  balance  is  much  superior  to  an  ordinary 
cast  iron  pulley. 

4.  Weight  being  less  than  cast  iron  pulleys,  admits  the  use  of 
lighter  shafting  and  hangers,  thus  reducing  the  weight  on  buildings 
and  saves  power  ordinarily  wasted  turning  useless  weight. 

STANDARD  m$c(&  STEEL  RIM  WHOLE  PULLEYS  ARE 
DESIGNED  FOR  SINGLE  OR  NORMAL  DOUBLE  BELT 
USAGE 

Extra  strong  pulleys  for  severe  duty,  either  with  extra  heavy 
arms  or  with  cast  steel  arms,  internally  flanged  rims,  etc.,  will  be 
made  to  order. 


m$c<&  STEEL  RIM  PULLEYS  ARE  ALSO  MADE  SPLIT  WITH 
INTERCHANGEABLE  BUSHINGS

NOTE— The  list  prices  given  on  pages  29  to  32  cover 
Steel  Rim  whole  Pulleys.  These  pulleys  are  not  carried  in  stock, 
but  being  made  to  order  only  will  be  found  generally  somewhat  higher 
in  net  price  than  the  $&&(&  Steel  Rim  Split  Pulleys  with  Inter- 
changeable Bushings  (in  the  sizes  listed  on  page  20  only),  the  reason 
being  that  the  interchangeably  bushed  pulleys  are  made  up  in  large 
quantities,  thus  reducing  the  cost  of  manufacture. 


Details  to  be  considered  when  ordering 
m&<&  STEEL  RIM  WHOLE  PULLEYS 

Also  read  all  instructions  on  pages  12  to  15. 

These  pulleys  are  manufactured  in  two  different  styles: 

First — Solid  Rim  and  Solid  Hub. 

Second — Solid  Rim  and  Split  Hub.     (Called  clamp  hub  pulleys). 

They  are  also  furnished  in  pairs  as  tight  and  loose,  with  hubs 
full  length  of  face.  See  additional  price  list  on  page  56. 

All  M&(&  Pulleys  over  19  inches  face  have  two  or  more  rows 
of  arms. 

Smallest  diameter  9  inches,  largest  diameter  108  inches.  Widest 
face  48  inches. 

Crown  face  M$c(&  Pulleys  cannot    be    made    with    faces    much 
wider  than  their  diameters.     (Subject  to  the  limitations  given  above.) 
Pulleys  cannot  be  furnished  with  offset  arms. 
Pulleys  cannot  be  furnished  with  plate  centers. 

iU  &  (&  Pulleys  are  all  furnished  setscrewed  without  extra  charge. 
If  keyseats  are  also  wanted,  see  price  list  for  keyseating  on  page  56. 

Standard  hubs  are  not  faced.    For  facing  hubs  see  list  on  page  56. 

$i$c(&  Pulleys  ordered  with  fine  fractional  bores,  fractional  or 
exact  diameters  or  faces,  long  or  offset  hubs,  etc.,  are  all  subject 
to  an  extra  charge.  See  page  15. 

M$c(&  Pulleys  are  balanced  for  a  rim  speed  of  3000  feet  per 
minute.  For  higher  speeds  special  balancing  is  required,  and  for 
which  an  extra  charge  is  made. 

M$c(&  Pulleys  with  excessively  large  bores  are  subject  to  an 
extra  charge.  See  bore  table  on  page  33. 

NOTE — The  price  list  on  next  four  pages  covers  standard  pulleys 
only.  For  definition  of  special  pulleys  read  pages  14  and  15.

PULLEYS  WITH  SPECIAL  HUBS 

Important  instructions  for  ordering  pulleys  with  special    hubs 
or  hubs  in  any  way  departing  from  our  standard  hubs  as  shown  on 
page  33  for  m$c<&  Whole   Pulleys   and    page   51  for   C.  I.  I 
whole  or  split. 

STANDARD  PULLEY  WITH 
STANDARD  HUB 

Face  is  nominal  and  is  always  wide 
enough  to  carry  belt  of  width  given. 

Diameter  is  nominal  and  measured  at 
the  crown. 

Hubs  and  arms  are  central. 

Hubs  are  of  lengths  (L)  given  in  table. 

(For  il&<&  Steel  Rim  Pulleys  see 
page  33.) 

(For  C.  I.  Pulleys  see  page  51.) 

For  Double  Arm  Pulleys  the  Double 
Hub  is  central  and  of  the  total  length  as 
given  in  tables  mentioned. 

Standard  Hubs  are  not  faced  unless 
so  ordered  and  for  which  an  extra  charge 
is  made  as  per  list  on  page  56.

OFFSET  HUBS 

By  "Offset  Hubs"  is  meant  hubs 
"offset"  or  moved  over  relative  to  center 
line  of  pulley,  whether  single  or  double 


arm. 

The  total  offset  of  the  longest  part  of 
hub  in  pulley'here  shown  is  the  distance 
X  and  must  be  mentioned  in  ordering, 
also  give  the  total  length  (L)  of  hub  if 
important — thus : 

"One  C.  I.  Pulley,  24  in.  dia.,  10  in. 
face,  2&  bore,  K.  S.  hub  7  inches  long, 
offset  5  inches." 

Example  No.  2 

IMPORTANT  NOTE— Offset  hubs  are  always  faced  ON  THE  OFFSET  C 
LONGEST  END  only,  unless  both  ends  are  ordered  faced. 

When  taper  keyways  are  ordered  in  offset  hubs  we  always  cut  the  deep  part 
of  keyway  at  the  short  side  of  the  hub  unless  otherwise  ordered.

OFFSET  HUB— EXTENDING 
BEYOND  THE   FACE  OF 
PULLEY    ON    ONE   SIDE 

This  style  of  hub  is  to  be  ordered 
with  the  same  wording  as  example 
No.  2  shown  on  preceding  page,  being 
particular  to  mention  the  facing  of 
ends  of  hubs,  direction  of  driving  of 
taper  keys,  etc. 

Unless  otherwise  ordered,  we  face 
the  long  end  of  offset  hubs  only. 


NOTE— If  this  distance  is  important,  it  must  be  stated  thus:  "EXTENSION 

inches,"  but  in  that  case  the  distance  X  should  not  be  given  as  the  face 

being  but  nominal,  the  two  figures  would  conflict. 


FACE 


OFFSET  HUB— EXTREME  CASE 

This  cut  illustrates  an  offset  hub  so 
far  offset  as  to  require  the  arms  being 
moved  out  of  center  which  in  the  case 
of  very  wide  face  pulleys  or  double  arm 
pulleys  cannot  be  done,  nor  can  it  be 
done  with  4E&<£  Steel  Rim  Pulleys 
as  these  always  require  arms  placed 
in  center  of  rim. 


Example  No.  4 

In  ordering  this  style  use  same  wording  as  given  on  preceding 
page  at  example  No.  2  and  in  case  figures  given  make  it  impossible 
to  carry  out  we  will  so  advise. 

IMPORTANT— See  note  at  bottom  of  page  34  regarding  facing  of   hubs  and 
direction  of  driving  of  taper  keys.

Also  state  length  of  hub  if  important. 


NOTE-- On  "flush"  hub  pulleys  if  it  is 
desired  to  have  the  hub  extend  slightly  beyond 
rim  for  clearance,  the  extension  must  be  specified 
otherwise  it  will  be  in  line  with  edge  of  rim. 


Example  No.   5 

We  always  face  the  "flush"  end  of  hub  but  not  the  other  end 
unless  specified,  and  if  Taper  K.  S.  is  ordered  we  cut  deep  part  at 
the  short  side  of  the  hub  unless  otherwise  ordered.

NOTE— On  "flush"  hub  pulleys  if  it  is  desired 
to  have  the  hub  extend  slightly  beyond  rim

PRESSED  STEEL  SPLIT  PULLEYS 
"AMERICAN" 

American  Pulleys  are  made  entirely  of  wrought  steel.  They  are  "split"  pulleys 
for  double  belt  service  and  are  used  with  interchangeable  bushings.  No  keyways  or 
set  screws  are  required  unless  in  special  cases,  when  keys  can  be  used. 

They  weigh  about  half  as  much  as  cast  iron  pulleys,  and  being  split  can  be 
applied  without  stripping  the  shaft. 

They  grip  the  shaft  to  perfection  and  can  be  bushed  down  to  any  size  of  shaft. 


Design  used  Sizes  6"  to  24"  (Patented) 
(In  Narrow  Faces  only  above  16") 


Design  used  sizes  16"  to  24"  (Patented) 

(Wide  Faces) 

Same  Design  all  Faces  25"  to  42"  except  that 
wide  faces  have  two  or  more  rows  of  arms. 


Design  used  in  Sizes  3"  to  5"- 
Diameter,  inclusive 


(Patented) 
Design  used  in  Sizes  44"  to  60"  Diameter 


Metal  Bushings  to  Fit  any  Shaft 


For  Price  List  of  American  Steel  Split  Pulleys  see  pages  60  to  62. 

TO  FIND  HORSE  POWER  WHICH  AN  "AMERICAN"  PULLEY  WILL 

SAFELY  TRANSMIT 
(Formula  given  by  the  manufacturers.) 

Multiply  the  circumference  of  the  pulley  in  feet  (C),  by  the  number  of  revolu- 
tions per  minute  (R),  by  the  width  of  the  pulley  face  in  inches  (W),  by  125,  and 
divide  by  33,000.  Thus: 

Horse  Power= — - 

33,000 

The  figures  given  for  the  horse  power  which  pulleys  will  transmit  are  much 
too  high  to  be  a  safe  guide  in  the  case  of  belting.  To  find  what  a  double  belt  will 
transmit  make  the  formula 

Horse  Power=CxRxWx75

CAPILLARY  BRASS  BUSHINGS 

These  bushings  pictured  above  are  made  solid  only  and  are  pressed  tightly  into  pulley  hubs.  Large 
oil  chamber  is  provided  from  which  oil  is  fed  by  capillarity  through  felt  wicks  to  the  shaft. 

Prices  will  be  quoted  on  application  as  cost  depends  on  lengths  wanted  on  account  of  pattern 
work.  In  asking  for  prices  give  exact  length  of  pulley  hub  and  state  whether  we  are  to  fit  bushing 
into  hub.

And  a  careful  perusal  of  the  facts  presented  will  explain  why  the 
Gilbert  Wood  Split  Pulley  is  steadily  gaining  in  sales  year  by  year, 
in  spite  of  the  many  patent  pulleys  now  in  competition  with  it.

GILBERT  WOOD  SPLIT  PULLEYS  (Continued) 

A  FEW  REASONS  WHY  WOOD    PULLEYS   ARE   GOOD   PULLEYS   AND 
GILBERT  WOOD  PULLEYS  ARE  THE  BEST  WOOD  PULLEYS 

It  has  been  clearly  demonstrated  by  practical  experience  that  maple  presents 
a  better  surface  than  any  other  wood  adaptable  for  pulleys.  It  is  very  hard,  close 
and  fine  grained. 

The  face  of  a  maple  pulley  in  use  soon  takes  a  high  polish,  which  gives  more 
perfect  contact  to  belt. 

Gilbert  Wood  Split  Pulleys  weigh  very  much  less  than  either  solid  or  split 
iron  or  steel  pulleys. 

Gilbert  Wood  Split  Pulleys  have  a  better  belt  surface  than  iron  or  steel  pulleys. 
Haswell,  the  acknowledged  authority,  and  most  quoted  by  American  mechanics, 
summarizes  thus:  "The  ratio  of  friction  to  pressure  for  leather  belts,  when  run  over 
wooden  pulleys,  is  47;  over  turned  cast-iron  pulleys,  24."  Consequently,  equal 
power  can  be  transmitted  with  less  tension  on  the  belt,  which  results  in  a  saving 
in  the  cost  of  belting,  by  prolonging  its  life,  and  which  reduces  the  strain  on  the  shaft- 
ing and  the  friction  of  the  journal,  thus  adding  to  the  advantages  obtained  by  the 
lighter  weight  of  the  wood  pulley  in  saving  frictional  loss  in  power  and  in  permitting 
the  use  of  lighter  shafting  and  hangers. 

Gilbert  Wood  Split  Pulleys  can  be  put  on  or  taken  off  the  shaft  very  easily, 
simply  and  quickly.  They  are  in  correct  balance  and  run  true  and  are  safe  under 
heavy  loads  and  at  high  speeds.  They  do  not  get  out  of  round  and  will  withstand 
more  severe  shocks  and  greater  compression  than  other  pulleys. 

Gilbert  Pulleys  meet  with  little  atmospheric  resistance,  as  the  spokes  are  set  to 
cut  the  air,  not  to  fan  it  and  collect  dust,  as  the  spokes  of  many  other  pulleys  do. 
This  makes  a  greater  difference  in  the  power  required  than  is  generally  supposed. 

Gilbert  Pulleys  have  a  perfect  compression  shaft  fastening.  The  wood  bushing 
(furnished  to  fit  any  shaft)  takes  a  tighter  hold  on  the  shaft  than  set  screws  do,  but, 
unlike  them,  does  not  injure  the  shaft. 

Gilbert  Wood  Split  Pulleys  will  withstand  a  greater  degree  of  heat  or  of  moist- 
ure than  other  wooden  pulleys,  on  account  of  the  material  of  which  they  are  made 
and  the  way  in  which  they  are  built  and  finished. 

Gilbert  Wood  Split  Pulleys  are  perfect  in  every  mechanical  detail,  and  the 
greatest  care  is  used  in  their  manufacture. 

We  carry  in  stock  at  all  times  a  large  and  complete  assortment  of  standard 
sizes  from  3  inches  in  diameter  upward.

GILBERT  WOOD  SPLIT  PULLEYS  (Continued) 
DESCRIPTION  OF  THE  VARIOUS  STYLES 


STYLE  C  STOCK  PULLEY 

As  made  in  sizes  3  to  14 

inches  diameter. 


Made  of  thoroughly  seasoned  maple,  case  hardened,  and  finished  with  two  coats 
of  varnish. 

It  is  bolted  together — the  nuts  on  the  clamping  bolts  being  covered  with  sectional 
blocks  which  cannot  get  out  of  place. 

When  putting  the  pulley  on  a  shaft,  all  its  parts  are  accessible  from  the  face. 

By  using  different  bushings,  the  same  pulley  may  be  made  to  Jit  different  sizes  of 
shafting. 

Made  in  sizes  from  3  to  14  inches  in  diameter. 

Our  Style  C  Pulley  is  regarded  almost  universally  as  incomparably  superior 
to  any  similar  article  manufactured. 


STYLE  B  STOCK  PULLEY 

(Four  spoke] 

As  made  in  sizes  12  to  24 
inches  diameter. 


Pulleys  from  12  inches  to  24  inches  in  diameter,  inclusive,  are  constructed  with 
four  sets  of  spokes,  as  shown  here. 

Pulleys  from  25  inches  to  70  inches  in  diameter,  inclusive,  are  constructed  with 
six  sets  of  spokes. 

Pulleys  larger  than  70  inches  in  diameter  have  eight  sets  of  spokes. 

Made  of  thoroughly  seasoned  maple,  the  rim  is  both  nailed  and  glued,  case 
hardened,  and  finished  with  two  coats  of  varnish. 

Each  spoke  is  securely  dovetailed  into  and  glued  in  the  rim,  and  is  set  in  a  line 
running  direct  from  the  center  of  the  shaft  to  the  rim — thus  affording  its  utmost 
support. 

They  meet  with  little  atmospheric  resistance,  as  the  spokes  are  set  to  cut  the  air, 
not  to  fan  it  and  collect  dust,  as  the  spokes  of  many  other  pulleys  do. 

On  all  pulleys  over  14  inches  in  diameter,  plates  are  used  instead  of  washers 
for  the  nuts  on  hub  clamping  bolts,  thus  distributing  the  compression  over  the  entire 
length  of  the  hub. 

Every  pulley  is  perfectly  balanced,  the  rims  being  turned  inside  as  well  as  out- 
side. 

By  using  different  bushings,  the  same  pulley  may  be  made  to  fit  different  sizes 
of  shafting.  Price  List  of  Stock  Pulleys  on  pages  74  and  75.

Gilbert  Special  Pulleys  with  iron  centers,  are  built  from  2  inches^,  in  diameter 
up  to  240  inches.  The  solid  web  iron-center  pulley,  known  as  the  Style  "D,"  is  built 
from  2  inches  up  to  72  inches  in  diameter;  and  the  spoke  pulley  with  iron  center, 
known  as  the  Style  "A,"  is  built  from  24  up  to  240  inches  in  diameter.  For  all  kinds 
of  exceptionally  heavy  work  or  high  speeds,  these  are  the  strongest,  truest-running 
pulleys  known.  Thousands  have  been  in  use  for  years,  some  of  them  running  at 
terrific  peripheral  speeds.  Drop-forge  work,  brick-making,  cement-making,  saw- 
mill hogs  and  edgers,  severe  idler  and  tightener  work,  trip-hammers  and  main  drives 
are  some  of  the  severe  uses  to  which  the  special  Gilbert  Special  Pulleys  are  par- 
ticularly adapted.

"CUMBERLAND  TURNED  AND  GROUND" 
STEEL  SHAFTING 


TRADE  MARK 


We  are  Pacific  Coast  agents  for,  and  carry  in  stock,  "Cumber- 
land Turned  and  Ground"  Steel  Shafting,  an  article  perfectly  round, 
smooth,  straight  and  true  in  size.  It  is  the  strongest  and  most  perfect 
shafting  in  the  market. 

A   FEW  WORDS  ON  SHAFTING 

We  desire  to  call  your  attention  to  the  following  remarks  re- 
garding Cumberland  Turned  and  Ground  Shafting: 

To  some  customers,  who  are  not  well  informed,  one  shaft  is  as 
good  as  another;  the  price  is  the  only  thing  they  care  to  consider. 
There  are  others  who  consider  quality  as  well  as  price.  To  these 
two  classes  of  buyers  we  would  direct  our  remarks. 

When  several  manufacturers  claim  they  make  the  best,  how  are 
you  to  decide  among  them?  You  cannot,  unless  you  have  tried 
each  kind  or  have  been  properly  informed  in  regard  to  the  difference. 

It  is  generally  known  that  Turned  Shafting,  when  properly 
made,  is  more  desirable,  as  there  is  no  lamination  of  the  surface  of 
the  metal,  nor  is  it  subjected  to  internal  strains. 

Taking  it  for  granted  that  Turned  Shafting  is  the  best,  is  there 
any  difference  in  Turned  Shafting?  Any  first-class  mechanic  knows 
that  it  is  almost  impossible  to  turn  a  shaft  perfectly  round  or  parallel, 
owing  to  the  difference  in  metal,  wear  of  tools,  etc.,  and  if  he  uses  a 
file  to  make  it  true  he  does  not  succeed.  When  necessary  to  have  a 
perfect  surface,  he  will  grind  it.  That  is  just  what  is  done  in  the 
manufacture  of  "Cumberland  Turned  and  Ground"  Shafting,  and  it 
is  the  difference  between  Cumberland  Shafting  and  that  made  by  all 
other  manufacturers. 

The  advantages  of  Turned  and  Ground  Shafting  are:  First, 
being  round  and  straight  it  can  be  run  at  a  very  high  speed  without 
heating  of  journals;  Second,  being  very  highly  polished  it  is  more  at- 
tractive in  appearance  —  the  surface  being  free  from  lamination 
makes  it  very  desirable  for  piston  rods,  etc.  ;  Third,  having  no  internal 
strains  due  to  the  process  of  manufacture,  it  is  very  desirable  where 
strength  is  required,  preventing  accidents,  loss  of  time,  money  and 
lives.  Fourth,  being  true  to  size,  couplings,  gearings,  etc.,  can  be 
fitted  at  less  cost. 

"Cumberland  Turned  and  Ground"  Shafting  embraces  all  sizes 
from  \T&  to  5H.  Smaller  sizes  are  furnished  in  cold  drawn;  larger 
sizes  in  hammered  steel.

*For  ordinary  transmission  of  power  involving  no  bending,  a  good  grade  of 
shafting  may  be  used  for  50  per  cent  more  H.  P.  than  given  in  table,  but  for  head 
shafts  and  heavy  work  it  is  advisable  to  use  40  per  cent  less  than  H.  P.  given  in  table.

KEYS  AND  KEYSEATING 

Machine  keys  are  of  two  kinds — straight  and  tapered. 

For  pulleys,  sprockets,  sheaves;  etc.,  we  have  adopted  as  our  standard,  the 
straight  key  with  straight  keyseats  cut  to  a  depth  of  one-half  the  width  of  key  in 
both  shaft  and  hub,  plus  a  slight  clearance  in  hub  (for  bur  caused  by  setscrews) 
as  shown  at  "D"  in  sketch  below. 

Depth  of  keyseats  for  taper  keys  is  as  given  in  table  on  next  page. 

Straight  Keys  are  always  furnished  unless  taper  keys  are  specifically  mentioned 
in  ordering. 

Setscrews  are  always  supplied  over  straight  keys. 


A  =  Width  of  Key. 

B  =  Depth  of  Keyseat  in  shaft. 

C  =  Depth  of  Keyseat  in  hub. 

D  =  Clearance  for  bur  caused 
by  setscrews  and  is  about  ^ 
inch  for  shafts  up  to  2^  inch. 
•^  inch  for  shafts  from  2^  to 

5H; 

33o  inch  for  shafts  above  5^. 


STRAIGHT  KEY 

(Made  with  round  or  squareends) 


PLAIN  TAPER  KEY 


GIB  HEAD  TAPER  KEY 

T=  Thickness  at  large  end  to 
correspond  with  total  depth  of 
keyseat  at  deep  end. 


A  =  Width  of  Key. 


Drilled  End  Keyseat  or  Featherway 


Standard  Keyseat,  (with  ends  as  left  by  milling  cutter) 


"Length  of  Keyseat"  always  means  "over  all"  or  from  the  extreme  ends. 
Table  of  Standard  Taper  and  Straight  Keyways  is  given  on  next  page — price 
list  for  cutting  Keyways  on  page  80. 

SPECIAL  NOTE — When  shafts  only  are  ordered  with  Keyseats,  we  will  cut 
them  suitable  for  our  standard  taper  keys  (see  dimension  table  next  page)  unless 
exact  width  and  depth  is  specified  on  the  order. 

For  example: — 1  shaft  1  yf  xlO  feet  long  to  have  Keyseat  12  inches  long  in  center. 

We  would  cut  a  Keyseat  Yi  inch  wide  by  f»  mcn  deep  by  12  inches  long.

"HALLOWELL"  COLD  ROLLED  STEEL  (Patented) 


With  Counter  Sunk 
Setscrew 


The  perfected  "Hallowell"  Safety  Shaft  Collar  of  Cold  Rolled  Steel  is  so  neat 
and  highly  polished  that  it  improves  the  looks  of  any  piece  of  machinery. 

Yet  it  costs  less  than  common  cast  iron  collars  though  made  of  a  far  superior 
material. 

Made  solid  in  the  smaller  sizes  and  of  pressed  steel  in  the  larger  sizes. 

It  positively  won't  crack. 

And  the  setscrew  can't  possibly  strip  the  threads. 

The  "Hallowell"  is  safe  because  setscrew  is  harmless  by  not  projecting.

BOLTED  FLANGE  COUPLINGS 


Bolted  Flange  Couplings  are  the  standard  for  all  classes 
of  work  and  especially  for  heavy  shafting.  They  are  supplied  with 
turned  bolts  passing  through  reamed  holes  and  the  flanges  are  care- 
fully faced,  turned,  bored  and  keyseated. 

When  ordered  placed  on  shafts  at  our  works,  the  flanges  are 
pressed  on  shafts  under  hydraulic  pressure,  firmly  keyed  in  place 
with  taper  keys  and  then  faced  off  to  perfect  alignment  with  shafts. 

When  not  fitted  to  the  shafts  at  our  works,  plain  taper  keys  are 
furnished  with  couplings.

UNIVERSAL  JOINT  COUPLINGS 


STYLE  A 

CAST  IRON  UNIVERSAL  JOINT  SHAFT  COUPLING 
(See  also  Style  B  on  page  102) 

These  Universal  Joint  Couplings  are  used  for  shaft  connections 
where  the  angle  of  shafts  does  not  exceed  thirty  degrees  from  a  straight 
line;  though  it  is  better  to  keep  the  angle  much  less  than  this  if  possible. 

They  work  smoothly  and  silently,  and  for  all  moderate  speeds  will 
be  found  superior  to  bevel  gearing. 

We  offer  our  patrons  the  choice  of  two  styles  of  Universal  Joint 
Couplings — the  "Style  A"  shown  on  this  page  being  our  regular 
design,  the  body  and  pin  block  are  made  of  cast  iron,  and  the  pins  of 
steel. 

The  hubs  are  secured  to  the  shafts  by  means  of  keys  and  headless 
setscrews. 

This  style  of  coupling  has  proven  thoroughly  reliable  in  every  way. 

The  other,  "Style  B"  is  an  all-steel  coupling  carried  in  the  smaller 
sizes  only.  See  description  on  page  102.

STEEL  UNIVERSAL  JOINT  COUPLINGS 


STYLE  B 

STEEL  UNIVERSAL  JOINT  SHAFT  COUPLING 
See  also  Style  A  on  page  100. 

This  style  of  Universal  Joint  Coupling  is  made  entirely  of  steel 
with  hardened  working  parts.  It  possesses  superior  wearing  qualities 
and  the  ability  to  withstand  a  thrust  or  tension.  When  ordered 
"fitted  for  shafts"  the  ends  are  bored  out  to  fit  shafts  and  supplied 
with  taper  pins  to  hold  shafts  in  position  after  same  are  driven  in  place. 

The  working  angle  of  these  couplings  is  purposely  limited  as 
given  in  table  on  next  page,  as  by  so  doing,  the  parts  which  take  the 
twisting  strain  are  supported  just  so  much  nearer  the  center  of  joint 
and  chance  for  wear  and  unnecessary  strains  which  might  be  caused 
by  running  at  too  great  an  angle,  if  unlimited,  is  reduced.  Forty-five 
degrees  is  as  much  as  can  be  expected  of  any  Universal  Joint  to  run 
at  and  not  over  25  or  30  degrees  should  be  used  where  a  greater  angle 
can  be  avoided.  The  smaller  the  angle  at  which  they  are  run  the 
longer  they  will  wear  and  less  power  they  will  absorb.

FLEXIBLE  COUPLINGS 
LEATHER  LINK  TYPE 


m$c<&  Leather 

Link 
Flexible  Coupling 


These  couplings  allow  of  considerable  displacement 
from  true  alignment  of  shafts  and  are  very  smooth  in 
action. 

They  effectually  insulate  the  ends  of  shaft  from  each 
other  which  is  an  important  feature  in  some  cases. 

Shafts  may  be  disconnected  if  desired  by  removing 
the  studs  from  the  discs  through  the  slots  in  the  opposite 
disc. 

Solid  leather  links  are  used  as  pictured  above — these 
links  are  much  stronger  than  the  "wrapped"  open  links 
formerly  used. 

NOTE  —  When  Flexible  Couplings  are  wanted  for 
reversing  shafts,  offset  pins  and  open  links  are  supplied, 
which  alters  the  price  and  H.  P.  rating  given.

FLEXIBLE  COUPLINGS 
LEATHER  BAND  TYPE 


ii&(g  Leather 

Band 
Flexible  Coupling 


In  this  style  of  flexible  coupling  the  separate  leather  links  are 
dispensed  with  and  an  endless  leather  band  is  used.  The  band  passes 
in  and  out  of  the  cast  lugs  as  shown  and  the  ends  are  cemented  to- 
gether as  with  an  endless  leather  belt. 

This  coupling  is  made  of  three  parts  as  shown  in  the  sketch 
below,  and  may  be  disconnected  by  removing  the  cap  screws  which 
secure  the  outer  ring  in  position. 

If  it  is  desired  to  run  with  the  coupling  disconnected,  the  member 
to  which  the  outer  ring  is  attached  should  be  mounted  on  the  driving 
shaft  so  that  the  ring  when  disconnected  may  be  supported  by  the 
dead  shaft.

Cut  shows  it  fitted  with  an  M$c(&  Steel  Rim  Whole  Pulley. 

Our  "Perfection"  Belt  Tightener  illustrated  above  was  especially 
designed  for  heavy,  vertical  belts. 

It  travels  in  an  arc  thrown  from  lower  pivot  and  has  two  cast 
iron  racks  formed  to  the  same  curve. 

It  will  work  either  to  the  right  or  left  and  can  be  locked  at  any 
position  by  simply  turning  the  clamping  handle  shown  in  front  of 
hand  wheel. 

The  bearing  is  on  a  sleeve  full  length  of  pulley  face — fitted  with 
grease  cups  and  provided  with  anti-drip  pockets. 

At  present  we  have  but  one  size,  which  was  designed  to  take  a 
pulley  up  to,  and  including,  36  inches  diameter  by  24  inches  face, 
though  it  may  be  fitted  with  any  smaller  diameter  or  narrower  face 
pulley  if  desired. 

Price  does  not  include  pulley.  Select  any  suitable  pulley  in  our

It  is  similar  to  the  screw  belt  tightener  shown  on  page  110,  though 
not  quite  so  heavy. 

The  bearings  are  babbitted  ring-oiling  and  have  long  screw 
adjustment  operated  by  means  of  the  handwheels  shown  in  the  cut. 

Bearings  are  pivoted  in  the  adjusting  yokes  to  prevent  binding 
in  case  both  sides  are  not  adjusted  equally. 

It  is  chiefly  used  for  horizontal  belts  and  may  be  suspended  from 
the  ceiling  or  placed  on  the  floor  in  the  position  shown  in  the  above  cut. 

Price  does  not  include  pulley — select  any  pulley  in  our  list  within 
the  capacity  of  the  tightener  desired  and  add  its  price  to  price  of 
tightener  given  below.

PLAIN  SWING  BELT  TIGHTENER 

Shown  equipped  with  an  fH&(£  Steel  Rim  Whole  Pulley 

This  Belt  Tightener  is  the  well-known  '  'Swinging  Frame"  style. 

It  is  simple,  effective  and  can  be  applied  in  almost  any  position. 
In  most  cases  the  combined  weight  of  frame  and  pulley  acting  by 
gravity  alone  is  sufficient  to  produce  proper  tension  on  belt,  but  at 
some  angles  of  application,  it  may  be  desirable  to  use  additional 
weight,  which  can  readily  be  done  either  by  attaching  to  frame  or  by 
means  of  ropes  attached  to  eyebolts  on  frame — the  ropes  to  be  passed 
over  idler  sheaves  and  supplied  with  proper  weights. 

Pulley  Bearings  are  babbitted  and  supplied  with  grease  cups — 
the  bearings  can  be  turned  around  and  secured  in  any  position  so  as 
to  admit  of  grease  cups  being  placed  at  any  angle. 

This  Belt  Tightener  is  made  in  four  sizes,  each  suitable  for  the 
maximum  size  pulley  listed  below,  although  the  frames  may  be 
ordered  with  any  smaller  size  pulley  desired. 

Price  does  not  include  pulley.  Select  any  pulley  from  our  list 
within  the  capacity  of  the  frame  wanted  and  add  its  price  to  price 
of  Tightener  given  below.

COUNTER-WEIGHTED  BELT  TIGHTENER 

Cut  shows  it  equipped  with  an  M$c<&  Steel  Rim  Whole  Pulley. 

This  style  of  Belt  Tightener  is  counterweigh  ted  to  produce  proper 
pressure  against  the  belt  and  the  weight  can  be  adjusted  along  the 
lever  to  secure  any  desired  tension. 

The  lever  bar  can  be  set  at  any  angle  on  the  shaft,  either  in  back 
or  in  front  of  the  pulley,  thus  permitting  tightener  to  be  used  on 
belts  running  in  any  plane  whatsoever. 

The  tightener  can  either  be  suspended,  or  supported  from  below 
on  hangers  (as  shown  in  cut),  or  dolly  boxes  can  be  used,  this  feature 
depending  on  the  particular  conditions  involved. 

The  frames  are  made  in  three  sizes,  each  to  take  maximum  pulley 
as  listed  below,  but  they  may  be  fitted  with  smaller  pulleys  if  desired. 

Prices  given  below  include  a  pair  of  shaft  hangers,  but  not  the 
pulley.  Select  any  pulley  in  our  list  within  the  capacity  of  tightener 
desired  and  add  its  price  to  that  of  tightener  given  below.

"  SHORTCENTER"   Belt   DriVC 


THE    PRINCIPLE 


Shortcenter  Belt  Drives  are  the  result  of  a  gradual 
development  in  the  application  of  idlers  in  belt  driving. 

This  subject  has  been  given  a  great  deal  of  attention  of  recent 
years,  especially  in  Europe,  where  the  combined  features  of  the 
system  as  generally  adopted  are  known  under  names  such  as  "Lenix" 
drives,  etc.,  and  our  design,  embodying  the  result  of  experience  to 
date  with  these  drives  and  the  knowledge  gained  by  the  study  of 
thousands  of  belt  drives  of  all  kinds,  has  been  named  the  Jtt&(i 
Shortcenter  Belt  Drive. 

As  shown  in  the  diagram  above,  it  consists  principally  of  the 
proper  application  of  a  specially  designed  resilient  idler  pulley,  and 
while  the  use  of  idler  pulleys  under  spring  pressure,  swinging  belt 
tighteners,  etc.,  is  not  new,  the  former  having  been  used  for  many 
years  as  an  attachment  on  motors — the  study  of  the  underlying 
principles  and  scientific  application  is  new,  as  it  has  been  found 
possible  to  install  shortcenter  belt  drives  in  many  cases  where  for- 
merly high  speed  chain  drives  were  always  used. 

Speed  ratios  such  as  1  to  6,  1  to  7,  1  to  8  with  very  short  centers 
are  common  and  even  higher  ratios  as  1  to  10,  etc.,  are  quite  possible. 

The  power  obtainable  with  a  given  width  of  belt  is  also  con- 
siderably higher  than  for  ordinary  drives — sometimes  as  much  as 
100  per  cent  greater. 

Permanency  of  the  installations  is  all  that  can  be  desired, 
as  a  correctly  designed  drive  will  run  for  years  with  no  attention, 
save  oiling,  and  is  not  to  be  compared  with  a  high  speed  chain  drive 
in  general  freedom  from  annoyance  and  smoothness  of  running. 

The  application  of  the  IB  &(6  Shortcenter  Belt  Drive  is  very  broad 
and  covers  light  high  speed  devices  to  heavy  transmissions  of  power. 
On  the  following  pages  we  show  a  few  characteristic  drives. 

As  the  fH&(&  Shortcenter  Belt  Drive  is,  strictly  speaking,  an 
engineering  proposition,  and  must  be  designed  to  meet  the  special 
conditions  of  each  case,  to  insure  success  we  ask 'those  requiring 
Shortcenter  Belt  Drives  to  answer  fully  all  the  questions  given  on 
page  127  when  writing  for  prices.

Step  off  the  plies  as  shown,  being  careful  not  to  cut  plies  beneath 
the  portion  removed.  Scrape  exposed  duck  carefully  and  coat  with 
at  least  three  coats  of  rubber  cement  allowing  one  to  dry  before  put- 
ting on  the  next.  When  the  last  coat  is  tacky  place  ends  of  belt  to- 
gether and  pound.  Then  punch  and  sew  with  narrow  lace  leather, 
or  rivet  with  copper  rivets  and  burrs. 
For  Price  List  of  Rubber  Belting  see  page  129. 


TO  FIND  LENGTH  OF  BELT 

In  cases  where  pulleys  are  of  nearly  the  same  diameter  and  are  at  considerable  distances,  a  fairly 
accurate  and  easy  rule  is  as  follows: — Add  the  diameter  in  inches  of  the  driving  and  the  driven 
pulleys;  multiply  this  sum  by  3^  and  divide  by  2.  To  the  number  thus  obtained,  add  twice  the 
distance  from  center  of  shafts  in  inches,  and  the  result  will  be  the  length  of  the  belt  (without  lap) 
in  inches. 

A  more  exact  method  of  determining  the  length  of  belt  necessary  to  connect  two  pulleys  on  dif- 
ferent shafts  is  as  follows: 

-  (R-r)2  +  (R  3.1416  -f  r  3.1416)  in  which  L  is  the  distance 
R  is  the  radius  of  the  large  pulley  in  inches,    r  is  the  radius 


Length  of  belt  without  lap  =  2  V7L2 
from  center  to  center  of  shafts  in  inches, 
of  the  small  pulley  in  inches.

HORSEPOWER  TRANSMITTED  BY  LEATHER  BELTS 

The  table  below  is  for  properly  designed  drives  using  best  quality 
of  double  leather  belting  Y%  inch  thick,  and  is  figured  to  allow  for  the 
tension  of  slack  side  and  the  effect  of  centrifugal  force. 

The  figures  are  based  on  a  working  strain  of  340  Ibs.  per  square 
inch  of  cross  section  and  an  arc  of  contact  on  pulley  of  160  degrees. 

For  other  angles  of  contact  multiply  the  H.  P.  of  table  by  the

BELT  TRANSMISSION 

The  transmission  of  mechanical  power  from  one  shaft  to  another 
may  be  accomplished  in  many  ways — belts,  ropes,  cables,  gears,  chain, 
frictions,  etc.,  and  some  of  the  methods  have  been  brought  to  a  high 
state  of  efficiency,  but  it  is  safe  to  say  that  Belt  Drives  still  lead, 
and  perhaps  always  will  lead  all  other  methods  of  transmitting 
motion  from  shaft  to  shaft  in  industrial  plants. 

The  reason  for  the  maintained  supremacy  is  the  simplicity  of 
this  method,  its  flexibility,  low  cost,  and  efficiency  when  properly 
installed. 

When  direct  motor  drives  came  forward  a  few  years  ago,  it  was 
generally  thought  that  motors  connected  direct  to  all  machines 
would  in  time  displace  entirely  the  method  of  driving  by  means  of 
belts — but  while  individual  motor  drives  are  of  great  value  in  some 
cases,  they  have  on  the  whole,  not  made  much  progress  against 
properly  designed  belt  transmission. 


BELT  DRIVES  VS.  DIRECT  CONNECTED  MOTOR  DRIVES 

The  following  words  from  the  pen  of  the  late  Mr.  F.  W.  Taylor, 
an  authority  on  scientific  shop  management,  are  of  interest  in  this 
connection.  He  said: 

"The  writer  is  firmly  convinced,  through  large  personal  observa- 
tion in  many  shops  and  through  having  himself  systematized  two 
electrical  works,  that,  in  perhaps  three  cases  out  of  four  a  properly 
designed  belt  drive  is  preferable  to  the  individual  motor  drive  for 
machine  tools.  There  is  no  question  that  through  a  term  of  years 
the  total  cost,  on  the  one  hand,  of  individual  motors  and  electrical 
wiring,  coupled  with  the  maintenance  and  repairs  of  this  system, 
will  far  exceed  the  first  cost  of  properly  designed  shafting  and  belting 
plus  maintenance  and  repairs.  There  is  no  question,  therefore,  that 
in  many  cases  the  motor  drive  means  in  the  end  additional  complica- 
tion and  expense  rather  than  simplicity  and  economy." 

NOTE — The  italics  are  ours. 

However,  Belt  Drives  to  give  satisfaction  must  be  properly 
designed  to  accomplish  the  work  for  which  they  are  intended,  and 
while  the  standard  text  books  are  full  of  data  on  the  subject,  we  think 
that  the  data  given  on  the  preceding  two  pages  and  that  to  follow  will 
enable  the  practical  man  to  select  the  proper  size  belt  for  any  drive 
he  may  wish  to  install,  though  we  are  ready  at  all  times  to  assist 
through  our  Engineering  Department  in  the  proper  proportioning 
of  pulleys,  etc.,  to  secure  the  best  results.

BELT  TRANSMISSION  (Continued) 

SPEED — It  must  be  remembered  that  while  more  horsepower  can  be 
transmitted  by  increasing  the  speed  of  belts,  the  increase  is  not 
proportionate  to  speed,  but  falls  off  rapidly  above  4800  feet  per 
minute,  due  to  the  action  of  centrifugal  force. 

HORSEPOWER— The  figures  given  in  table  on  page  133  make  al- 
lowance for  centrifugal  force,  and  may  be  used  for  any  thickness 
or  style  of  belt  by  using  the  various  modifying  factors  given  on 
pages  132  and  133. 

LEATHER  BELTING— Used  with  the  hair  or  grain  side  to  the  pulleys 
is  what  such  horsepower  figures  are  usually  based  on,  as  the  co- 
efficient of  friction  is  somewhat  better — sometimes  rated  as  30 
per  cent  greater  than  the  flesh  side — though  this  is  open  to  ques- 
tion. 

CRACKING  OF  LEATHER  BELTS— Leather  belts  run  the  flesh 
side  out  are  less  liable  to  crack  than  when  reversed  as  the  fibers 
of  the  flesh  side  are  more  flexible. 

SLACK  SIDE  AND  TIGHT  SIDE— The  slack  side  should  always 
be  uppermost  if  possible,  and  the  tight  side  underneath,  as  the 
arc  of  contact  on  the  small  pulley  is  thereby  increased. 

LAGGED  PULLEYS— On  difficult  drives  leather  lagging  on  pulleys 
may  be  resorted  to,  as  it  increases  the  traction  from  30  to  about 
50  per  cent  over  plain  metal  rims. 

DISTANCE  BETWEEN  CENTERS— In  ordinary  belt  drives  much 
depends  on  the  distance  between  centers,  and  as  a  rule,  with 
certain  limits,  the  longer  the  better,  as  it  increases  the  arc  of  con- 
tact and  provides  more  "spring"  in  the  belt  to  maintain  contact 
on  pulleys. 

RULE  FOR  CENTERS— A  rule  for  proper  centers  covering  any 
drive  is  hard  to  give,  but  it  may  be  generally  stated — make  it 
four  times  the  diameter  of  the  largest  pulley  minus  the  diameter 
of  the  other  pulley — but  never  less  than  8  or  9  feet  for  ordinary 
work.  This  is  approximate  only  as  much  depends  on  conditions. 

VERY  SHORT  CENTERS— Very  short  centered  drives  may  be  suc- 
cessfully installed   by   resorting   to    resilient   idler   pulleys — see 
"SHORTCENTER"  Drives  on  page  122.

BELT  TRANSMISSION  (Continued) 


ANGULAR  AND  QUARTER  TURN  DRIVES— Belts  may  be  suc- 
cessfully run  over  pulleys  that  are  not  parallel  to  each  other  by 
observing  the  following  rule:  The  center  of  the  face  of  the  driving 
pulley  where  belt  leaves  the  pulley  must  be  in  line  with  the  center 
of  the  face  of  the  driven  pulley  where  the  belt  leaves  the  pulley;  in 
other  words,  the  centers  of  the  faces  at  the  leaving  sides  must  be  in 
line-,  such  drives  should  be  made  of  very  long  centers  to  get 
the  best  result,  and  are  not  reversible  unless  the  relation  of  the 
pulleys  is  also  reversed.  See  cuts  below.

Plan  views  of  quarter  turn  and  angle  drives,

as  dotted  at  "B"  and  "C".  These  distances  de- 
pend on  the  nature  of  the  belt,  but  Bach,  hi

OIL  WELL  COUNTERSHAFT 


When  the  electric 
motor  was  introduced 
in  the  oil  fields,  its 
economy  and  conven- 
ience soon  insured  it  a 
permanent  place. 

However,  owing  to 
its  speed  of  rotation  be- 
ing much  higher  than 
the  steam  engine  for- 
merly used,  the  matter 
of  reducing  the  speed 
was  met  by  a  counter- 
shaft. 

iH  &  (&  Oil  Well  Countershafts  were  the  first  successful  counter- 
shafts used  in  the  California  fields  and  the  new  model  above  pictured 
is  still  a  long  way  ahead  of  all  others. 

This  countershaft  is  principally  used  in  oil  well  operations,  but 
is  also  very  useful  in  other  work  where  a  massive  countershaft  is 
required. 

The  4ft  &(£  Oil  Well  Countershaft,  as  now  made,  embodies 
several  distinct  improvements  over  the  models  of  several  years  ago 
and  is  fortified  against  every  weakness  developed  by  the  daily  use 
of  the  earlier  models  at  hundreds  of  wells  in  the  California  fields. 

The  new  model  is  of  very  massive  construction.  Has  long  ring 
oiling  bearings  with  reservoir.  Lower  half  of  bearings  planed  and 
recessed  to  receive  the  caps  which  are  also  planed  and  held  immovable 
when  in  position.  A  number  of  sheet  steel  liners  are  accurately  fitted 
between  upper  and  lower  parts  of  bearings  to  facilitate  adjustment 
for  wear. 

The  frame  is  fitted  with  heavy  planed  sliding  rails  which  are  not 
separate  as  in  the  older  models  but  are  cast  together  in  one  rigid 
piece  to  hold  all  in  perfect  alignment  and  to  allow  belt  tension  to  be 
regulated  by  the  turn  of  a  single  adjusting  screw  and  which  may  be 
done  without  stopping  the  motor  or  disturbing  the  alignment. 

The  use  of  a  heavy  single  pulling  screw  for  adjusting  while  the 
planed  guides  preserve  the  alignment  is  a  great  improvement  over 
the  old  style  in  which  two  lighter  pushing  screws  were  used  for 
adjusting  and  which  also  had  to  be  manipulated  to  maintain  the 
alignment  of  pulleys.

'THE  REEVES"  VARIABLE  SPEED  TRANSMISSION 

''The  Reeves"  Variable  Speed  Transmission  is  applicable  to  any 
machine  of  whatever  nature  requiring  speed  changes. 

Wherever  step  cones,  taper  cones,  expanding  pulleys,  gears, 
variable  speed  engines,  motors  or  other  devices  have  been  used, 
"The  Reeves"  Variable  Speed  Transmission  may  be  applied. 

It  is  made  in  sizes  to  transmit  any  amount  of  power  up  to  150 
horsepower  —  to  perform  any  range  of  variation  from  2  to  1  to  10  to  1. 

It  gives  quickly,  any  speed 
between  fastest  and  slowest, 
without  stopping;  does  not 
step  from  one  speed  to  an- 
other but  gives  a  gradual 
change,  steady  power  and 
perfect  control  of  the 
machine  driven.  A  turn  of  a 
crank  secures  any  speed  you 
need. 

The  frame  is  of  cast  iron,  in  two  pieces,  hangers  cast  solid  with 
frame.  The  main  boxes  have  ring-oiling  bearings,  and  the  hubs  of 
the  disks  work  against  special  roller-thrust  bearings.  Friction  is 
reduced  to  the  minimum  and  the  efficiency  is  very  high. 

The  Transmission  may  be  suspended  from  the  ceiling  or  set  upon 
the  floor,  and  used  the  same  as  an  ordinary  countershaft.  Belt 
from  the  line  shaft  to  the  constant  shaft  of  the  Transmission,  and 
from  the  variable  shaft  to  the  machine  to  be  driven.  Either  shaft 
may  be  used  as  driver  or  driven. 

IN  MAKING  INQUIRY  of  us  as  to  the  size  of  Transmission 
required  for  driving  any  machine  the  following  data  should  be  given  us: 

1  —  Kind  of  machine  to  be  driven. 

2  —  Diameter  of  drive  pulley  on  the  machine. 

3  —  Width  of  belt  used  on  this  pulley. 

4  —  Whether  double  or  single  belt  is  used. 

5  —  Highest  speed  it  is  desired  to  run  this  pulley. 

6  —  Lowest  speed  it  is  desired  to  run  this  pulley. 

7  —  Speed  of  line  shaft  from  which  Transmission  will  be  driven. 

8  —  Whether  Transmission  is  to  be  used  on  floor  or  ceiling. 

Before  recommending  the  size  of  Transmission  for  driving  any 
given  machine,  we  must  have  complete  data  concerning  same. 
Send  sketches  if  possible. 

A  large  special  catalog  on  "the  Reeves"  Transmission  will  be  sent 
on  request.

Figure  2 

Figure  2  shows  exactly  the  opposite 
conditions,  whereby  the  V  belt  on 
the  driving  shaft  assumes  the  largest 
driving  surface  and  the  driven  the 
smallest,  thus  propelling  the  driven 
shaft  at  its  maximum  speed. 


Figure  1 

Figure  1  shows  disks  on  driving 
shaft  separated  to  admit  V  belt  to 
the  smallest  driving  surface  and  the 
disks  on  the  driven  shaft  brought  to- 
gether, so  that  the  V  belt  assumes  the 
greatest  driving  surface,  thus  pro- 
pelling the  driven  shaft  at  its  mini- 
mum speed. 

HOW  IT  OPERATES 

Two  pairs  of  cone-shaped  disks  "C"  are  spline  mounted  on  two 
parallel  shafts  ''A"  and  "B".  These  disks  have  their  apexes  facing 
and  are  movable  on  the  shaft,  and  are  operated  by  pivoted  levers 
"D",  which  are  actuated  by  a  screw  "E"  in  such  manner  as  to  bring 
one  pair  of  disks  together  while  the  other  pair  is  separated  an  equal 
distance,  and  at  the  same  time  preserve  a  uniform  tension  of  the 
special  V  belt. 

The  faces  of  these  disks  form  a  V-shaped  groove  into  which  is 
fitted  the  specially  designed  V  belt,  having  its  bearing  surface  on 
the  edges  instead  of  the  bottom,  as  an  ordinary  belt. 

The  belt  is  fitted  with  hardwood  blocks,  of  precisely  the  same 
length,  bolted  to  the  belt  body,  the  ends  of  these  blocks  being  given 
the  proper  angle  to  fit  the  faces  of  the  disks,  and  tipped  with  leather. 

Proper  tension  of  the  belt  may  be  maintained  by  adjusting  the 
take-up  screws  "F". 

One  pair  of  disks  acts  as  driver  and  runs  at  a  constant  speed. 
The  other  pair  acts  as  driven  and  runs  at  varying  speeds.  As  the 
disks  on  the  constant  shaft  are  brought  together  so  the  belt  assumes 
the  larger  diameter  on  same,  the  disks  on  the  variable  shaft  are  sepa- 
rated so  the  belt  assumes  the  smaller  diameter  and  the  speed  is  in- 
creased. When  the  opposite  condition  prevails,  the  speed  is  de- 
creased. The  shifting  screw  "E"  is  operated  by  a  small  hand-crank 
which  is  turned  one  direction  to  increase  the  speed  and  the  opposite 
direction  to  reduce  it. 

Price  list  is  given  on  page  143.

Referring  to  maximum  and  minimum  horsepower,  as  shown  in 
the  table,  the  maximum  horsepower  shown  is  the  power  that  the 
Transmission  will  deliver  from  the  variable  shaft  when  the  constant 
speed  shaft  is  run  at  the  maximum  revolutions  indicated  in  the  table, 
and  the  "V"  belt  is  at  the  largest  diameter  of  the  disks  on  this  shaft. 

The  minimum  horsepower,  as  shown,  is  the  power  that  the 
Transmission  will  deliver  from  the  variable  shaft  when  the  constant 
speed  shaft  is  run  at  the  speed  indicated  in  the  table,  and  the  "V" 
belt  is  at  the  smallest  driving  diameter  it  assumes  on  this  shaft. 

The  various  Transmissions  will  carry  the  size  pulley  shown,  or 
its  equivalent,  on  the  variable  shaft.  Working  stress  of  belt,  60 
pounds  per  inch  of  width. 

The  constant  speed  shaft  must  not,  under  any  condition,  be 
run  at  a  greater  speed  than  indicated  in  the  table;  it  may  be  run  at 
a  lesser  speed,  but  in  this  event,  the  power  transmitted  will  be  propor- 
tionately decreased. 

We  will  not  be  responsible  for  the  successful  operation  of  the 
Transmission  if  instructions  are  not  complied  with. 


General  Design,  Nos.  7  to  10,  inclusive,  illustrating  Power  Shifting  Device. 

The  larger  sizes  are  the  same  in  principle  as  the  smaller-  sizes, 
except  that  they  have  heavy  cast  iron  bases,  and  are  built  very  strong 
to  withstand  extra  hard  service. 

They  have  either  hand  or  power  shifting  device. 

On  sizes  Number  8  and  above,  the  disks,  instead  of  being  driven 
by  keys  in  the  shafts  are  equipped  with  pin  drive.

ENGINEERING  DATA  AND  FORMULAS 

In  compiling  this  edition  of  our  catalog,  we  have  endeavored 
wherever  possible  to  give  data  and  engineering  formulas  relating  to 
our  goods  at  the  various  lists  or  description  of  such  goods,  so  that  such 
information  would  be  found  automatically  by  customers  looking  up 
the  various  goods. 

But  in  some  cases  this  procedure  has  not  been  possible;  owing 
either  to  the  broad  nature  of  the  data,  or  to  the  listed  goods  (for 
instance,  Pulleys)  running  through  many  pages  of  the  book;  and 
data  of  this  kind  will  be  found  on  the  following  pages. 

In  this  section  No.  1  of  our  general  catalog  we  have  included 
at  the  end  of  the  book,  a  certain  amount  of  general  data  of  an 
engineering  nature,  having  no  bearing  on  the  goods  listed,  but  likely 
to  be  of  value  to  mechanical  men  generally. 

Data  pertinent  to  goods  listed  in  other  sections  of  our  general 
catalog  will  also  be  found  at  the  end  of  the  respective  sections  unless 
given  at  the  various  lists  of  goods.

RULES 

F'or  Determining  Size  and  Speed  of  Pulleys  (or  Gear  Wheels*) 

The  driving  pulley  is  called  the  Driver,  and  the  driven  pulley 
the  Driven. 

To  determine  the  diameter  of  Driver,  (the  diameter  of  the  Driven 
and  its  revolutions,  and  also  revolutions  of  Driver  being  given.) 

Diameter  of  Driven  x  revo^tions  of  Driven 

r  _^  .  ~  =  Diameter  of  Driver. 

Revolutions  of  Driver 

.     To  determine  the  diameter  of  Driven,   (the  revolutions  of  the 
Driven,  and  diameter  and  revolutions  of  the  Driver  being  given.) 

Diameter  of  Driver  x  revolutions  of  Driver 

—  :  —  :  —       r  _.   .  —  ~  =  Diameter  of  Driven. 

Revolutions  of  Driven 

To  determine  the  revolutions  of  the  Driver,  (the  diameter  and 
revolutions  of  the  Driven,  and  diameter  of  the  Driver  being  given.) 

Diameter  of  Driven  x  revolutions  of  Driven 


Diameter   of    Driver 


=  Revolutions  of  Driver. 


To  determine  the  revolutions  of  the  Driven,  (the  diameter  and 
revolutions  of  the  Driver,  and  diameter  of  the  Driven  being  given.) 

Diameter  of  Driver  x  revolutions  of  Driver 

~~:r: .  „  .  ~  =  Revolutions  of  Driven. 

Diameter  ot   Driven 

For  table  of  horsepowers  of  pulleys  see  opposite  page. 

*To  apply  the  above  rules  to  gear  wheels  simply  use  the  number  of  teeth  on 
the  wheels  in  place  of  the  pulley  diameters. 


DETERMINING    SPEED    OF    INTERMEDIATE    SHAFT    IN 
DOUBLE  REDUCTION  DRIVES 


When  the  revolutions  per  minute  of  shafts  "A"  and  "C"  are 
known,  to  determine  the  revolutions  per  minute  of  shaft  "B"  to 
maintain  uniformity  in  both  reductions,  use  the  following  formula: 

V  A  x  C  -  B 
(The  letters  referring  to  the  revolutions  per  minute  of  the  shafts.)

DEFINITION  OF  ELECTRICAL  TERMS 

The  mechanical  powers  in  modern  industry  are  in  final  operation 
closely  allied  with  all  electrical  matters  and  yet  the  business  of  me- 
chanical engineering  and  manufacturing  is  so  distinct  from  electrical 
engineering  and  manufacturing  that  we  have  not  included  any  elec- 
trical data  in  these  pages;  but  we  give  below  the  definition  of  some  of 
the  more  commonly  used  electrical  terms: 

ACCUMULATOR — A  term  used  to  designate  either  a  current  accu- 
mulator, a  condenser,  or  a  storage  battery. 

ALTERNATING  CURRENT— A  current  having  a  periodic  change 
in  direction,  the  product  of  an  alternating  current  generator. 

AMMETER — Any  kind  of  galvanometer  which  measures  the  strength 
of  a  current  in  amperes. 

AMPERE — The  Unit  of  electric  current — the  amount  of  current 
which  can  pass  through  a  circuit  offering  one  ohm  resistance, 
under  an  electromotive  force  of  one  volt. 

AMPERE  HOUR — An  amount  of  current  equal  to  one  ampere 
flowing  for  one  hour. 

ANODE — The  positive  pole  of  an  electric  battery,  or  where  the  cur- 
rent comes  out  of  a  battery.  ; 

CATHODE — The  negative  pole  of  an  electric  battery — the  pole  at 
which  the  current  re-enters  battery  after  having  passed  through 
the  circuit. 

CONTINUOUS  OR  DIRECT  CURRENT— A  current  flowing  in  one 
direction  only. 

E.M.F. — An  abbreviation  of  "Electromotive  Force." 

ELECTRODE — Either  one  of  the  electric  source  terminals  placed 
into  a  solution  where  electrolysis  is  going  on. 

Definition  of  electrical  terms  continued  on  next  page.

DEFINITION  OF  ELECTRICAL  TERMS  (Continued) 

ELECTROLYSIS — Chemical  decomposition  caused  by  the  action  of 
an  electric  current. 

GALVANOMETER — An  instrument  for  measuring  the  strength  of 
an  electric  current  by  the  deflection  of  an  electric  needle. 

HORSEPOWER  (ELECTRICAL)— An  amount  of  current  equal  to 
746  watts,  or  .746  kilowatts. 

KILOWATTS — One  thousand  watts  (about  one  and  one-third  horse- 
power.) 

OHM — The  practical  unit  of  electrical  resistance,  a  resistance  which 
would  limit  the  flow  of  a  current  to  one  ampere  under  an  electro- 
motive force  of  one  volt. 

OHMS  LAW — The  law  which  expresses  the  relation  between  current, 
electromotive  force  and  resistance: 

~  Electromotive  force         T       E 

Current  -    —5 — r—  or  I  =-B- 

Resistance  R 

p 
Hence  E  =  IR    and     R  =-p 

In  which   I  =  the  current  measured  in  amperes. 

E  =  the  electromotive  force  measured  in  volts. 
R  =  the  resistance  measured  in  ohms. 

SYNCHRONOUS  MOTOR— An  alternating  current  motor  which 
must  be  brought  in  step  with  the  driving  current  to  operate 
properly. 

VOLT — The  unit  of  electric  pressure,  or  electromotive  force.  The 
electromotive  force  necessary  to  cause  an  electric  current  of  one 
ampere  to  pass  through  a  resistance  of  one  ohm. 

VOLT  AMMETER — An  instrument  for  measuring  either  or  both 
volts  and  amperes  in  a  current. 

WATT — The  unit  of  electrical  power — the  result  of  one  ampere  of 
current  at  a  pressure  of  one  volt,  equal  to  44.25  ft.  Ibs.  per 
minute. 

WATTMETER — An  instrument  for  measuring  the  electric  current 
and  giving  the  reading  in  watts.
